Xa i-voltage inciphisiwe, i-motor, njengesixhobo esiphambili se-electric drive, idlula kuthotho lweenguqu ezibalulekileyo. Olu lulandelayo luhlalutyo oluneenkcukacha lwezi nguqu, oluyilelwe ukunceda ukuqonda ngcono impembelelo yokunciphisa i-voltage ekusebenzeni kwe-motor kunye neemeko zokusebenza.

一, Utshintsho lwangoku
Inkcazo yomgaqo: Ngokomthetho ka-Ohm, ubudlelwane phakathi kwe-current I, i-voltage U kunye ne-resistance R yi-I=U/R. Kwiimoto zombane, i-resistance R (ngokuyintloko i-stator resistance kunye ne-rotor resistance) ayitshintshi kangako, ngoko ke ukuncitshiswa kwe-voltage U kuya kukhokelela ngokuthe ngqo ekwandeni kwe-current I. Kwiintlobo ezahlukeneyo zeemoto zombane, utshintsho lwangoku luya kufana nolo lwe-stator resistance. Kwiintlobo ezahlukeneyo zeemoto, iimpawu ezithile zotshintsho lwangoku zinokuhluka.

Ukusebenza okuthe ngqo:
Iimoto zeDC: iimoto zeDC ezingenamabhrashi (BLDC) kunye neemoto zeDC ezibrashiweyo zifumana ukonyuka okukhulu kwamandla ombane xa i-voltage incitshisiwe ukuba umthwalo uhlala ungaguquki. Oku kungenxa yokuba imoto ifuna amandla ombane amaninzi ukugcina amandla ombane okuqala.

Iimoto ze-AC: Kwiimoto ezingasebenziyo, nangona imoto inciphisa isantya sayo ngokuzenzekelayo ukuze ilingane nomthwalo xa i-voltage inciphisiwe, umbane usenokunyuka kwimeko yomthwalo onzima okanye otshintsha ngokukhawuleza. Ngokuphathelele imoto ehambelanayo, ukuba umthwalo awutshintshi xa i-voltage inciphisiwe, umbane awuyi kutshintsha kakhulu ngokwethiyori, kodwa ukuba umthwalo uyanda, umbane uya kwanda nawo.

二、torque kunye notshintsho lwesantya

Utshintsho lwe-torque: Ukunciphisa i-voltage kudla ngokukhokelela ekunciphiseni i-torque ye-motor. Oku kungenxa yokuba i-torque ihambelana nemveliso yamandla ombane kunye ne-flux, kwaye xa i-voltage yehlisiwe, nangona i-current inyuka, i-flux inokuncipha ngenxa yokungabikho kwe-voltage, nto leyo ebangela ukwehla kwe-torque iyonke. Nangona kunjalo, kwezinye iimeko, njengakwii-DC motors, ukuba i-current yonyuswe ngokwaneleyo, inokubuyisela ukwehla kwe-flux ukuya kwinqanaba elithile, igcine i-torque izinzile.

Utshintsho lwesantya: Kwiimoto ze-AC, ngakumbi iimoto ezingatshintshiyo nezihambelanayo, ukwehla kwe-voltage kuya kubangela ngokuthe ngqo ukwehla kwesantya. Oku kungenxa yokuba isantya semoto sinxulumene nokuphindaphinda kombane kunye nenani leepali zeemoto, kwaye ukwehla kwe-voltage kuya kuchaphazela amandla entsimi ye-electromagnetic yemoto, nto leyo enciphisa isantya. Kwiimoto ze-DC, isantya silingana ne-voltage, ngoko ke isantya siya kuncipha ngokufanelekileyo xa i-voltage incipha.

Ngokusebenza kakuhle kunye nobushushu
Ukusebenza okuphantsi: i-voltage ephantsi iya kukhokelela ekusebenzeni okuphantsi kwe-motor. Ngenxa yokuba i-motor ekusebenzeni kwe-voltage ephantsi, ifuna i-current engaphezulu ukugcina amandla okukhupha, kwaye ukwanda kwe-current kuya kwandisa ukulahleka kobhedu kunye nokulahleka kwesinyithi kwe-motor, ngaloo ndlela kunciphisa ukusebenza kakuhle kwayo iyonke.
Ukwanda kokuveliswa kobushushu: Ngenxa yokwanda kwamandla ombane kunye nokusebenza kakuhle okunciphileyo, iimoto zivelisa ubushushu obuninzi ngexesha lokusebenza. Oku akukhawulezisi nje kuphela ukuguga nokuguguleka kwemoto, kodwa kunokubangela ukusebenza kwesixhobo sokukhusela ubushushu obugqithisileyo, nto leyo ekhokelela ekucinyweni kwemoto.

Impembelelo kubomi bemoto
Ukusebenza ixesha elide phantsi kwe-voltage engazinzile okanye kwindawo ye-voltage ephantsi kuya kuyifinyeza kakhulu ubomi benkonzo yemoto. Kuba ukuncipha kwe-voltage okubangelwa kukwanda kwamandla ombane, ukuguquguquka kwe-torque, ukwehla kwesantya kunye nokunciphisa ukusebenza kakuhle kunye neminye imiba kuya kubangela umonakalo kwisakhiwo sangaphakathi kunye nokusebenza kombane kwemoto. Ukongeza, ukwanda kokuveliswa kobushushu kuya kukhawulezisa inkqubo yokuguga kwezinto zokukhusela iimoto.

五、Amanyathelo okuthintela
Ukuze kuncitshiswe impembelelo yokunciphisa i-voltage kwimoto, kunokwenziwa la manyathelo alandelayo:
Lungiselela inkqubo yobonelelo lwamandla: qinisekisa ukuba i-voltage yegridi yobonelelo lwamandla izinzile, ukuze kuthintelwe impembelelo yokuguquguquka kwe-voltage kwimoto.
Ukukhethwa kweemoto ezifanelekileyo: kuyilo nasekukhethweni kokuguquguquka kwevolthi, qwalasela ngokupheleleyo izinto ezibangela ukukhethwa kweemoto ezinoluhlu olubanzi lokuguquguquka kwevolthi.
Faka isiqinisi sombane: faka isiqinisi sombane okanye umlawuli wombane kwindawo yokungena kwemoto ukuze ugcine uzinzo lombane.

Qinisa ukugcinwa: uhlolo oluqhubekayo kunye nokugcinwa kwemoto ukuze kufunyanwe kwaye kujongwane neengxaki ezinokubakho ngexesha elifanelekileyo ukuze kwandiswe ubomi benkonzo yemoto.
Ngamafutshane, impembelelo yokunciphisa i-voltage kwimoto inamacala amaninzi, kuquka utshintsho lwangoku, utshintsho lwe-torque kunye nesantya, ukusebenza kakuhle kunye neengxaki zobushushu kunye nempembelelo yobomi bemoto. Ke ngoko, kwiindlela ezisebenzayo kufuneka kuthathwe amanyathelo asebenzayo okunciphisa ezi ziphumo ukuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwemoto.
